Complexation mechanism of dextrin with metal hydroxides [PDF]

open access: yes, 1998
The complexation of dextrin with metal hydroxides was studied quantitatively by FT-IR and UV-visible reflectance spectroscopic techniques. Though three hydroxyl groups are present in each dextrin molecule, complexation involving only two hydroxyl groups ...

Synthesis of (±)-trans-2,5-Diisopropylborolane

open access: yesMolecules, 2001
The cyclic hydroboration of 2,7-dimethyl-2,6-octadiene (6) was studied. It was found that the stereochemical outcome of the reaction was dependent upon the solvent, temperature, time and the nature of the borane reagent.

Proton and cadmium adsorption by the archaeon Thermococcus zilligii: Generalising the contrast between thermophiles and mesophiles as sorbents [PDF]

open access: yes, 2010
Adsorption by microorganisms can play a significant role in the fate and transport of metals in natural systems. Surface complexation models (SCMs) have been applied extensively to describe metal adsorption by mesophilic bacteria, and several recent ...

Complexation-Initiated Intramolecular Diels−Alder Reaction

open access: yes, 2016
A complexation-initiated intramolecular Diels−Alder reaction was demonstrated for the first time. On adsorbing the alkyne−Co2(CO)6 complexes having a diene and a dienophile on opposite ends of the alkyne on silica gel, the Diels−Alder reaction was ...

EXAMINATION OF THE POSSIBILITY OF ENHANCING THE PHYTOREMEDIATION POTENTIAL OF PLANTS THROUGH COMPLEXATION OF ALKALINE SOIL

open access: yesJournal of Sustainable Technologies and Materials
This study presents the results of applied phytoextraction as a soil phytoremediation method, based on the analysis of selected heavy metal content in soil and plant material. The selected locations where phytoextraction was applied as a phytoremediation

Spectrophotometric Study of New Schiff Base Complexes with Some Metal Ions in Methanol Solution [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
The complexation reactions between N,N'-3,6-dioxa-1,8-octanebis (salicylaldimine) [saldioxen(I)] and Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II) were studied spectrophotometrically in methanol solution at 25 °C.
